Vaguely boat related, I guess.
Walking along the beach is always fun, and part of the fun are the things you find. Well, some of the things are pretty nasty, but picking up little bits of sea glass is fun. We've been doing it for about a year now and have a pretty good sized collection of shells and glass, as well as a few pieces of cool driftwood.
Brown (beer bottle), green (Heiniken) and white (Coke) glass are the most common, with yellow and blue harder to find. Red is very rare.
